A production process of enameled wire and a production device thereof

Abstract

The invention discloses a production device of enameled wire, which includes a mounting base, A wire drawing machine, a quenching device, a tempering device, a cutting-coating device, a lacquer dry device and a winding packaging device are sequentially installed on the mounting base from left to right, , the invention also provides a production process of enameled wire, relying on enamelled wire production equipment to carry out wire drawing cleaning, heat treatment of conductive copper core, cuting and coating of the hybrid shield, paint drying, and on-line detection packaging. As that mix protective layer is coated and the heat treatment is carried out, The mechanical strength and toughness of the enameled wire are enhanced, cracks in the enameled wire are prevented, and the enameled wire is painted and dried by the way of soaking paint and vertical traction and baking, thus ensuring the uniformity of the thickness of the insulating paint on the enameled wire, and greatly improving the production quality and working performance of the insulating paint.

Description

technical field [0001] The invention relates to the field of enameled wire production, in particular to an enameled wire production process and production equipment. Background technique [0002] Enameled wire is a main variety of winding wire, which is composed of conductor and insulating layer. After the bare wire is annealed and softened, it is painted and baked many times. However, it is not easy to produce products that meet both standard requirements and customer requirements. It is affected by factors such as raw material quality, process parameters, production equipment, and the environment. Therefore, the quality characteristics of various enameled wires are different, but they all have Mechanical properties, chemical properties, electrical properties, thermal properties four major properties. [0003] Polyimide is currently the highest heat-resistant enameled wire enamel among organic enameled wires, and its long-term service temperature can reach above 220°C. Th...

Problems solved by technology

[0006] (1) The toughness of the enameled wire in the prior art is limited. When the enameled wire is bent with a large arc or is wound multiple times, cracks are likely to occur on the enameled wire, and the insulating varnish on the outside of the enameled wire will also fall off as a result, resulting in a decrease in the electrical isolation performance of the enameled wire. At the same time, the parallel connection between adjacent enameled coils reduces the resistance between the entire enameled wire coils. When the enameled wire is working, the It can be seen that under the condition of a certain working voltage, the smaller the resistance, the more heat generated on the resistance, and there is a safety hazard of burning electrical appliances;

[0007] (2) In the process of coating insulating varnish in the production equipment of enameled wire in the prior art, adopt felt to carry out the coating of insulating varnish, because the solidification of insulating varnish on felt, cause the thickness of insulating varnish coating on the conductive copper core to be inconsistent, at the same time During the drying process of the enameled wire, the inclination of the conductive copper core will easily lead to the centrifugal phenomenon of the insulating varnish, which makes the thickness of the insulating varnish on the enameled wire inconsistent, which greatly affects the production quality of the enameled wire
